[0020] 图1A图示依据一些实施例的放射系统10。 [0020] FIG 1A illustrates a system in accordance with some embodiments of the radiation 10. 放射系统10包括底座12、支撑部14、囊舱16、放射源18、准直器19、控制系统20和患者支撑部22。 The radiation system 10 includes a base 12, a support portion 14, the capsule 16, the radiation source 18, the collimator 19, the patient support system 20 and the control portion 22. 在图示的实施例中,底座12和支撑部14被制造成具有统一配置的单件。 In the illustrated embodiment, the base portion 12 and the support 14 are manufactured in one piece having a uniform configuration. 在其它实施例中,底座12和支撑部14可以是耦合在一起的分离部件。 In other embodiments, the base 12 and the support portion 14 may be separate components coupled together. 另外,在另外的实施例中,支撑部14可以是相对于底座12以一个或多个自由度可移动的。 Further, in another embodiment, the support portion 14 relative to the base 12 may be in one or more degrees of freedom movable. 在再另外的实施例中,底座12可以被认为是支撑部14的一部分。 In yet another embodiment, the base 12 may be considered part of the support portion 14.

[0021] 在图示的实施例中,囊舱16围绕轴28可旋转地耦合到支撑部14,并且限定用于容纳患者42的至少一部分40的空间30。 [0021] In the illustrated embodiment, the capsule 16 about the shaft 28 rotatably coupled to the support portions 14 and 30 define a space for receiving at least a portion 4042 of the patient's. 如本说明书中所使用的,术语“囊舱”可以指代至少部分地限定用于容纳对象(诸如患者42的部分)的空间的任何结构(其可以是单个部件或多个部件),并且不应被限制为提供全封闭的结构或者具有任何特定形状的结构。 As used in this specification, the term "capsule" may refer to at least partially define any structure for accommodating the object (such as a portion of the patient 42) a space (which may be a single member or multiple members), and not It should be limited to provide a fully enclosed structure, or structure having any particular shape. 在图示的实施例中,部分40为患者42的头部。 In the illustrated embodiment, the head portion 40 of the patient 42. 在其它实施例中,部分40可以包括患者42的(多个)其它部位。 In other embodiments, portion 40 may comprise (s) other parts of the patient 42. 例如,在其它实施例中,部分40可以包括患者42的头部和肩部这二者。 For example, in other embodiments, portion 40 may comprise both a patient's head and shoulder 42. 在另外的实施例中,部分40可以包括患者42的躯干。 In a further embodiment, the portion 40 may include a torso of the patient 42.

[0022] 如图所示,囊舱16包括第一囊舱部分50以及围绕轴54相对于第一囊舱部分50可旋转的第二囊舱部分52。 [0022] As shown, the capsule comprises a first capsule portion 16 and 50 about the axis 54 relative to the first capsule portion 50 of the second rotatable portion of the capsule 52. 在一个实施方式中,第一囊舱部分50和第二囊舱部分52可以使用舌槽机构而可旋转地彼此耦合,舌槽机构可以更有效地防止部分50、52的耦合之间的放射泄漏(因为舌槽机构的一部分可以衰减一些放射)。 In one embodiment, the first capsule portion 50 and a second capsule portion 52 may be rotatably coupled to one another using a tongue and groove mechanism, a tongue and groove mechanism can be more effectively prevent radiation leakage between the coupling portion 50, 52 (as part of the tongue and groove mechanism can be of some radiation attenuation). 在其它实施例中,第一囊舱部分50和第二囊舱部分52可以使用其它机构来耦合。 In other embodiments, the first capsule portion 50 and a second capsule portion 52 can be coupled using other mechanisms. 在图示的实施例中,第一囊舱部分50和第二囊舱部分52限定具有部分球形配置的内表面。 In the illustrated embodiment, the first capsule portion 50 and a second capsule portion 52 has an inner surface defining a part-spherical configuration. 在其它实施例中,内表面可以具有其它配置,并且不限于球形配置。 In other embodiments, the inner surface may have other configurations and is not limited to a spherical configuration.

[0023] 在图示的实施例中,囊舱16包括屏蔽材料,该屏蔽材料被配置成阻挡由放射源18的操作导致的至少一些放射。 [0023] In the illustrated embodiment, the capsule 16 comprises a shielding material, the shielding material configured to block at least some of the radiation from the radiation source 18 is operating. 屏蔽材料可以包括已知用于提供放射屏蔽的任何(多种)材料,包括但不限于钢、铅、钨或其组合。 A shielding material may comprise any known material (s) of the radiation shield, including but not limited to, steel, lead, tungsten, or combinations thereof. 在一些实施例中,屏蔽材料可以用于形成囊舱16的壁。 In some embodiments, the shielding material may be used to form the walls of the capsule 16. 在其它实施例中,屏蔽材料可以耦合到囊舱16的壁。 In other embodiments, the shielding material may be coupled to a wall of the capsule 16. 例如,屏蔽材料可以耦合到囊舱16的壁的外表面、囊舱16的壁的内表面或者可以是嵌在囊舱16的壁内的层。 For example, shielding material may be coupled to an outer surface of the wall of the capsule 16, the inner surface of the wall of the capsule 16 or may be embedded in the inner layer of the wall of the capsule 16. 此外,在其它实施例中,屏蔽材料可以是耦合到囊舱16的多层的形式,其具有耦合到囊舱16的壁的外表面的一个或多个层,嵌在囊舱16的壁内的一个或多个层,耦合到囊舱16的壁的内表面的一个或多个层,或者其组合。 Further, in other embodiments, the shielding material may be coupled to form a multilayer capsule 16, an outer wall having a surface which is coupled to the capsule 16 or a plurality of layers, embedded in the wall of the capsule 16 one or more layers, is coupled to an inner surface of the wall of the capsule 16 or more layers, or combinations thereof. 另外,在一些实施例中,屏蔽材料可以被配置(例如具有某一材料密度、某一几何形状和/或某一厚度)为阻挡放射,以使得它减少(衰减)从其行进经过的由放射源18的操作导致的放射(例如,光子/荷电粒子,诸如电子、中子等)的至少98%,以及更优选地至少99.9%,以及甚至更优选地至少99.999%。 Further, in some embodiments, shielding material may be configured (e.g., a material having a density, a geometry and / or a thickness) of blocking radiation, so that it is reduced (attenuated) by radiation from traveling through Radiation source 18 due to the operation (e.g., photons / charged particles, such as electrons, neutrons, etc.) of at least 98%, and more preferably at least 99.9%, and even more preferably at least 99.999%. 在另外的实施例中,屏蔽材料可以被配置成阻挡由放射源18的操作导致的足够数量的放射,以使得它消除在诸如医院或诊所之类的治疗设施处提供针对非职业性暴露的附加屏蔽的需要。 In a further embodiment, the shielding material may be configured to block sufficient amount of radiation by the operation of the radiation source 18, such that it eliminates in a hospital or treatment facility such as a clinic or the like to provide additional non-occupational exposure for shielding needs. 这种特征是有利的,因为它允许放射系统10可用于建筑物内的任何位置(假设系统10的重量不超过建筑物的负载承受能力),或者可用于任何设施处,而不要求对建筑物进行昂贵的改造以提供针对诸如阿尔法、贝塔、伽玛或中子之类的电离放射的屏蔽。 This feature is advantageous because it allows the radiation system 10 may be used in any location within the building (10 wt assumes that the system does not exceed the load bearing capacity of the building), or may be used in any facility, without requiring the building expensive engineered to provide for such ionized alpha, beta, gamma or neutron radiation shielding such. 在其它实施例中,不是完全消除建筑物处的屏蔽,屏蔽材料可以被配置成阻挡由放射源18的操作导致的足够数量的放射,以使得它减少在建筑物处的屏蔽要求的显著数量(例如至少50%,以及更优选地至少90% )。 In other embodiments, the shield building is not completely eliminated at the shielding material may be configured to block sufficient amount of radiation by the operation of the radiation source 18, such that it significantly reduces the number of shielding requirements at a building ( such as at least 50%, and more preferably at least 90%). 这种特征是有利的,因为它允许放射系统10可用于建筑物内的任何位置,或者可用于任何设施处,而对建筑物进行最小改造以提供放射屏蔽。 This feature is advantageous because it allows the radiation system 10 may be used in any location within the building, or may be used in any facility, for building and engineered to provide minimal radiation shield. 例如,针对整个房间的屏蔽要求可以被降低,或者仅仅房间的一(多个)部分可能需要针对屏蔽要求进行改造。 For example, shielding requirements for the whole room can be reduced, or only a part (s) of the room may need to be modified for the shielding requirements.

[0024] 在图1A的图示实施例中,放射源18为治疗放射源,其被配置成朝着等中心点提供治疗放射束,该等中心点与患者42的部分40中的目标区域吻合。 [0024] In the illustrated embodiment of FIG. 1A, the treatment radiation source to the radiation source 18, which is configured to provide a therapeutic radiation beam towards the isocenter, such patients target area coincide with the center point of the portion 40 42 . 放射源18可以能够响应于控制信号(例如来自控制单元的信号等)而被接通或断开。 The radiation source 18 may be in response to a control signal (e.g. a signal from the control unit or the like) is turned on or off. 可替换地,它可以是不能够被断开的放射性源,但是可以被快门式关闭(shutter)。 Alternatively, it may be turned off can not be a radioactive source, but may be closed the shutter (shutter). 放射源18可以在不同实施例中被配置成生成锥形束、扇形束或者其它类型的放射束。 The radiation source 18 may be configured to generate a cone beam in different embodiments, other types of fan beam or a radiation beam. 放射源18可以使用X频带线性加速器来实施。 The radiation source 18 may be implemented using an X-band linear accelerator. 在其它实施例中,放射源18可以使用其它类型的线性加速器来实施。 In other embodiments, the radiation source 18 may be implemented using other types of linear accelerators. 应当指出,如本说明书中所使用的,术语“放射源”或者诸如“源”之类的类似术语指代放射或能量从其发射的部件,并且可以包括或者不包括加速器。 It should be noted that, similar to the term, the term "radiation source" or as a "source" and the like in this specification refers to as used in the generation of radiation or energy emitted from the member, and may or may not include an accelerator. 另外,在图示的实施例中,放射源18被配置成提供具有下述能量水平的治疗放射束••从0.2MV到8MV的任何值,以及更优选地,从0.9MV到3MV的任何值。 Further, in the illustrated embodiment, the radiation source 18 is configured to provide a therapeutic radiation beam having the following •• energy level to any value from 0.2MV 8MV, and more preferably any value of from 0.9MV to 3MV . 在其它实施例中,放射源18可以被配置成提供具有诸如低于0.2MV或高于8MV之类的其它能量水平的治疗放射束。 In other embodiments, the radiation source 18 may be configured to provide other treatment radiation beam having an energy level such as below or above 0.2MV 8MV the like. 然而,提供具有3MV或更低的能量水平的放射束是更期望的,因为它可以避免需要添加屏蔽到设施的建筑物,或者至少降低建筑物的一些屏蔽要求。 However, 3MV providing radiation beam having an energy level or lower is more desirable, because it avoids the need to add to the building shielding facility, or at least reduce some of the shielding requirements of the building. 在其它实施例中,即使对于具有高于3MV的能量水平的放射束,也可以不要求对建筑物的屏蔽。 In other embodiments, even for a radiation beam having an energy level higher than the 3MV, it may not require shielding of the building. 这可以通过配置系统10的屏蔽(例如,提供更厚的屏蔽和/或使用(多种)更致密的材料等)来实现。 This system can be configured by mask 10 (e.g., provide a thicker mask and / or use (s) a more dense material, etc.) is achieved.

[0025]另外,在其它实施例中,可以结合紧密填充的屏蔽采用小束管来进一步减少放射暴露。 [0025] Further, in other embodiments, it may be combined with a small shielded tightly packed tube bundles to further reduce radiation exposure. 为了获得与束的紧密靠近以及进一步减小到目标的立体角,屏蔽可以被构建到加速器结构中,例如采用诸如Elkonite之类的致密传导材料。 In order to obtain a perspective angle in close proximity to the target and the beam is further reduced, the shield can be built into the accelerator structure, for example, a conductive material such as a dense Elkonite or the like. 借助电磁体或永磁体,蜿蜒束管可以被采用以阻挡到目标的视线以及辅助屏蔽放射暴露。 By means of an electromagnet or a permanent magnet, a serpentine tube bundle may be employed to block the line of sight to the target and the secondary shield radiation exposure. 示例将涉及偏转磁体(优选地消色差的)的使用。 Example involves the use of deflection magnets (preferably achromatic) a.

[0026] 在图示的实施例中,源到等中心点距离(SID)或者源-轴距离(SAD)小于800mm,以及更优选地小于600mm,以及甚至更优选地约为415mm (415mm±40mm)。 [0026] In the illustrated embodiment, the source to isocenter distance (SID) or a source - axis distance (SAD) less than 800mm, and more preferably less than 600mm, and even more preferably about 415mm (415mm ± 40mm ). 另外,在一些实施例中,放射系统10的SID/SAD值小于现有放射机器中的SID/SAD值。 Further, in some embodiments, SID / SAD value is smaller than the radiation system 10 in conventional radiotherapy machine SID / SAD value. 这种配置允许放射源18与现有治疗放射源相比提供更少的放射能量,并且仍然足以治疗目标(例如肿瘤或神经)。 This configuration allows the radiation source 18 as compared with the conventional treatment radiation source providing radiation of energy less, and still sufficient to treat the target (e.g. a tumor or a nerve). 另外,由于能量要求的降低,设施建筑物所需的屏蔽量大幅减少或者可能被消除。 In addition, due to reduced energy requirements, the amount of shielding required for installations of buildings significantly reduced or possibly eliminated. 另外,由于能量要求的降低,用于生成放射的加速器的尺寸可以被减小。 Further, due to the reduced energy requirements, the size of the accelerator for generating radiation can be reduced. 这进而减少系统10的重量,由此消除改造建筑物以支撑系统10的重量的任何需要,或者至少减少所要求的改造量。 This in turn reduces the weight of the system 10, thereby eliminating any need to transform the building to support the weight of the system 10, or at least reduce the amount of transformation required. 在其它实施例中,SID/SAD可以具有其它值。 In other embodiments, SID / SAD may have other values.

[0027] 如图1B所示,其为图1A的系统10的端视图,放射源18被倾斜以使得它相对于轴54形成角度80 (例如,非零锐角)。 As shown in [0027] Fig. 1B, which is an end view of the system 10 of FIG. 1A, the radiation source 18 is inclined so that it forms an angle 54 relative to the shaft 80 (e.g., a non-zero acute angle). 这种配置允许放射源18在第二部分52相对于第一部分50围绕轴54旋转时从不同角度朝着患者42的部分40递送放射。 This configuration allows the first part 50 is delivered from different angles about the axis of rotation 54 towards the patient 42, the radiation portion 40 in the radiation source 18 with respect to the second portion 52. 在其它实施例中,囊舱16可以围绕轴28旋转以围绕患者转动放射源18,以使得放射可以从不同角度被递送到患者。 In other embodiments, the capsule 16 may be rotated about the shaft 28 is rotated to the radiation source 18 about the patient, so that the radiation may be delivered to the patient from different angles. 在一些实施例中,部分52围绕轴54的旋转以及囊舱围绕轴28的旋转可以一个接一个地执行。 In some embodiments, a portion 52 may be performed by one around the rotation axis 28 and about the rotation shaft 54 ​​of the capsule. 可替换地,部分52围绕轴54的旋转以及囊舱围绕轴28的旋转可以同时执行。 Alternatively, the portion 52 may be performed simultaneously around the rotating shaft 28 around the rotational shaft 54 ​​and the capsule. 在一些实施例中,放射源18可以被配置成是相对于第二部分52可倾斜的。 In some embodiments, the radiation source 18 may be configured with respect to the second portion 52 may be inclined.

[0028] 回到图1A,准直器19紧挨着放射源18安置,并且被配置成依据治疗计划对来自源18的放射束成形。 [0028] Back to Figure 1A, the collimator 19 is disposed next to the radiation source 18, and is configured according to the treatment plan to the radiation beam from the source 18 is formed. 在一些实施例中,准直器19可以被认为是放射源18的一部分。 In some embodiments, the collimator 19 may be considered part of the radiation source 18. 如图所示,来自放射源18或准直器19的部件都不延伸到空间30内。 As shown, the member 18 from the radiation source or the collimator 19 does not extend into the space 30. 这形成囊舱16的内表面,该内表面与空间30内部的患者的部分保持空隙,由此避免当囊舱16围绕轴28旋转时和/或当第二囊舱部分52围绕轴54旋转时具有与在空间30内部的患者的部分碰撞的部件的风险。 This forms the inner surface of the capsule 16, in some patients the inner surface of the interior space 30 maintaining a space, thereby avoiding the capsule 16 when the surrounding and / or rotation of the shaft 28 when the second capsule portion 54 is rotated about the axis 52 risk in some patients with the member interior space 30 of the collision. 在其它实施例中,代替准直器,部件19可以是带有具有预定配置的出口的锥、提供具有可调节截面的出口的虹膜或者能够阻挡从放射源18提供的至少一些放射的任何其它设备。 In other embodiments, instead of the collimator, member 19 may be tapered with an outlet having a predetermined configuration, there is provided an adjustable iris having an outlet cross-section, or any other device capable of blocking at least some of the radiation from the radiation source 18 is provided . 在一个或多个实施例中,部件19可以被配置成阻挡/衰减至少98%的放射(例如在治疗场内),以及更优选地至少99.9%的放射(例如在治疗场外)。 In one or more embodiments, member 19 may be configured to block radiation / attenuation of at least 98% (e.g., in the treatment field), and more preferably at least 99.9% of the radiation (e.g. in the treatment of off-site).

[0029] 如图1A所示,囊舱16还包括用于允许患者42的部分40从其穿过以便到达囊舱16的内部空间30的开口60。 [0029] As shown in FIG. 1A, the capsule 16 further comprises a portion 40 for allowing the patient 42 to pass therethrough so as to reach the opening 60 of the inner space 30 of the capsule 16. 患者支撑部22包括桌台62,其用于支撑患者42 ;以及定位器64,其被配置成轴向地平移桌台62,以使得患者42的部分40可以穿过开口60被放置以到达空间30。 The patient support 22 includes the table portion 62, 42 for supporting a patient; and a retainer 64, which is configured to axially translate the table 62, so that the patient portion 40 through the opening 42 may be positioned to reach the space 60 30. 在其它实施例中,定位器64可以为桌台62提供其它(多种)移动。 In other embodiments, actuator 64 may provide other (s) to the table 62 moves. 例如,在其它实施例中,定位器64可以上下竖直地移动桌台62以允许患者42上到桌台62和/或将部分40与在囊舱16处的开口60对齐。 For example, in other embodiments, the locator 64 may be moved vertically up and down the table 62 to allow the patient 42 to the table 62 and / or the portion 40 aligned with the opening 60 in the capsule 16. 附加地或可替换地,水平平移可以用于将治疗容积相对于旋转轴定位在期望位置。 Additionally or alternatively, it may be used to treat horizontal translation with respect to the volume of the rotating shaft is positioned in a desired position. 在另外的实施例中,定位器64可以围绕竖直轴旋转桌台62,以由此相对于囊舱16将患者42安置在不同的角位置。 In a further embodiment, the retainer 64 about a vertical axis may be the table 62, to thereby with respect to the capsule 16 to the patient 42 disposed at different angular positions. 在图示的实施例中,患者支撑部22通过定位器64耦合到底座12。 In the illustrated embodiment, the patient support portion in the end retainer 22 coupled to base 1264. 这种配置允许支撑部22和囊舱16作为单个单元被运输。 This configuration allows the support portion 22 and the capsule 16 is transported as a single unit. 在其它实施例中,患者支撑部22可以与底座12分离。 In other embodiments, the patient support 22 may be separated from the base portion 12. 例如,在其它实施例中,患者支撑部22可以是独立于底座12可传输的。 For example, in other embodiments, the patient support 22 may be independent of the base 12 may be transmitted.

[0030] 在图示的实施例中,控制系统20包括耦合到控件82的处理器80,诸如计算机处理器。 [0030] In the illustrated embodiment, the control system 20 includes a control processor 82 is coupled to 80, such as a computer processor. 控制系统20还可以包括用于显示数据的监视器84以及用于输入数据的输入设备86,诸如键盘或鼠标。 The control system 20 may further comprise a monitor 84 for displaying data and an input device 86 for inputting data, such as a keyboard or a mouse. 在图示的实施例中,在成像和/或治疗程序期间,囊舱16围绕患者42旋转(如在CT程序和/或弓形疗法(arch-therapy)中那样)。 In the illustrated embodiment, during imaging and / or therapeutic procedure, the capsule 42 is rotated around the patient 16 (as in CT procedures and / or arcuate therapy (arch-therapy) in). 放射源18和囊舱16的操作由控件82控制,控件82提供电力和计时信号到放射源18和准直器系统19,并且基于从处理器80接收的信号,控制囊舱16的旋转速度和位置和/或部分52相对于部分50的旋转速度和位置。 Operating the radiation source 18 and the capsule 16 to provide power and timing control signals from the control 82, 82 to control the radiation source 18 and a collimator system 19, and based on signals received from the processor 80 controls the rotation speed of the capsule 16 and position and / or the rotational speed of the part 52 relative to part 50 and the location. 尽管控件20被示为与囊舱16和处理器80分离的部件,但是在可替换实施例中,控件20可以是囊舱16或处理器80的一部分。 Although the control 20 is shown as separate from the capsule 80 and the processor elements 16, but in an alternative embodiment, control 20 may be a part of the capsule 16 or the processor 80.

[0031] 在一些实施例中,系统10的部件(例如囊舱16、部分52等)的移动可以基于治疗计划来执行。 [0031] In some embodiments, the mobile components of system 10 (e.g., capsule 16, section 52, etc.) may be performed based on a treatment plan. 另外,在一些实施例中,当确定将使用系统10实施的治疗计划时,与系统10的移动部分的自由度关联的移动约束可以被结合到治疗计划中。 Further, in some embodiments, when determining a treatment plan using the system 10 embodiment, the degree of freedom of movement constraints associated with the moving part of the system 10 may be incorporated into the treatment plan.

[0032] 如图1A所示,放射系统10可以可选地还包括用于阻挡由放射源18的操作导致的放射的一个或多个屏蔽件90。 [0032] shown in FIG. 1A 10 radiation system may optionally further include one or more radiation shields blocking the radiation source 18 by the operation of 90.

(多个)附加屏蔽件90是有利的,因为它允许囊舱16阻挡更少的放射。 (S) additional shield member 90 is advantageous, because it allows the capsule 16 less radiation barrier. 例如,在一些实施例中,囊舱16处的屏蔽材料可以被配置成阻挡放射,以使得它衰减从其行进经过的由放射源18的操作导致的放射(例如,光子/荷电例子,诸如电子、中子等)的至少98 %,以及更优选地至少99.9 %,以及甚至更优选地至少99.999 %。 For example, in some embodiments, shielding material of the capsule 16 may be configured to block radiation so that it travels from the attenuation of radiation (e.g., photons / charged by the example of the operation of the radiation source 18 passes, such as at least 98% of the electrons, neutrons, etc.), and more preferably at least 99.9%, and even more preferably at least 99.999%. 在一些实施例中,囊舱16处的屏蔽材料以及(多个)附加屏蔽件90可以被配置成阻挡由放射源18的操作导致的足够数量的放射,以使得它们消除在设施建筑物(诸如在医院)提供屏蔽的需要。 In some embodiments, the shielding material 16 and the capsule (s) additional shield 90 may be configured to block sufficient amount of radiation by the operation of the radiation source 18, such that they eliminate installations of buildings (such as in the hospital) the need to provide shielding. 在其它实施例中,不是完全消除建筑物处的屏蔽,囊舱16处的屏蔽材料以及(多个)附加屏蔽件90可以被配置成阻挡由放射源18的操作导致的足够数量的放射,使得它们减少显著数量(例如至少50%,以及更优选地至少90% )的建筑物处的屏蔽要求。 In other embodiments, the shield building is not completely eliminated at the shielding material 16 and the capsule (s) additional shield 90 may be configured to block sufficient amount of radiation by the operation of the radiation source 18, such that they reduce a significant amount (e.g. at least 50%, and more preferably at least 90%) of the shield building requirements. 在其它实施例中,(多个)屏蔽件90可以被配置成阻挡由放射源18的操作导致的全部或大部分的放射。 In other embodiments, (s) the shield 90 can be configured to block all or most of the radiation from the radiation source 18 in operation. 在这种情况下,囊舱16可以不包括任何屏蔽材料。 In this case, the capsule 16 may not include any shielding material.

[0033] 应指出,(多个)屏蔽件90不限于在图示的实施例中所示的配置,并且在其它实施例中,(多个)屏蔽件90可以具有不同配置(例如形状)。 [0033] It should be noted (s) the shield 90 is not limited to the configuration shown in the illustrated embodiment, and in other embodiments, (s) the shield 90 may have a different configuration (e.g., shape). 例如,在其它实施例中,屏蔽件90可以为收纳患者42的部分(例如躯干、腿或二者等)的管或容器的形式。 For example, in other embodiments, shield member 90 may be in the form of the patient 42 to receive a portion (e.g. the torso, both legs or the like) of the tubes or containers.

[0034] 另外,如图1A所示,依据一些实施例,放射系统10可以可选地还包括成像器100。 [0034] Further, as shown in FIG. 1A, in accordance with some embodiments, the radiation system 10 may optionally further include an imaging device 100. 成像器(成像面板)100可以基于非晶硅或者任何本领域已知的其它技术。 Imager (imaging panel) 100 based on amorphous or any other techniques known in the art. 成像器100相对于源18安置在操作位置(例如,在囊舱16的与源18相对的一侧)。 The imager 100 with respect to the source 18 disposed in the operating position (e.g., on the side opposite the source 18 of the capsule 16). 在使用期间,来自放射源18的放射进入患者42并且离开患者42以到达成像器100。 During use, radiation from the radiation source 18 into the patient 42 and away from the patient 42 to reach the imager 100. 成像器100响应于在其上接收的放射而生成图像数据。 The imager 100 in response to radiation received thereon and generates image data. 放射在一些实施例中可以是治疗放射,或者在其它实施例中可以是诊断放射。 In some embodiments, the radiation may be radiation therapy, or in other embodiments may be diagnostic radiology. 在一些实施例中,图像数据可以在使用诊断放射的治疗过程之前(例如,在治疗放射被递送到患者42之前)生成以设定患者42。 In some embodiments before, the image data may be used in the diagnosis of radiation therapy (e.g., radiation treatment is delivered to the patient prior to 42) to set the patient 42 generated. 在其它实施例中,图像数据可以在治疗过程期间生成以强化治疗放射递送的准确性。 In other embodiments, the image data may be generated to enhance the accuracy of the delivery of radiation therapy during the course of treatment. 在另外的实施例中,图像数据可以由处理器80处理,处理器80基于经处理的图像数据调整治疗计划。 In a further embodiment, the image data may be processed by processor 80, processor 80 to adjust the treatment plan based on the processed image data. 例如,如果处理器80根据图像数据确定目标区域的一部分未在接收足够的放射,和/或如果关键(例如健康的)组织正在接收太多的放射,那么处理器80可以随后调整治疗计划,使得将来的治疗放射的递送将导致更多放射被递送到目标区域和/或更少放射被递送到关键组织。 For example, the processor 80 determines if a portion of the target region of the image data is not received sufficient radiation, and / or if the key (e.g., healthy) tissue too much radiation being received, the processor 80 may then adjust the treatment plan, such that the future of radiation therapy delivery will lead to more radiation being delivered to key organizational goal area and / or less radiation being delivered to.

[0064] 可替换地,从图3C所示的位置,承载放射源18的部分52可以围绕轴54旋转,以相对于部件160、50转动部分52。 [0064] Alternatively, the position shown in 3C, the portion 52 carrying the radiation source 18 may surround the rotation shaft 54 ​​with respect to the rotating portion 52 part 160,50. 例如,在第二部分52已经围绕轴54旋转了90°之后,系统10将具有图3E所示的配置。 For example, after the second portion 52 has been rotated 90 ° about the axis 54, the system 10 having the configuration shown in FIG 3E. 在所示示例中,放射源18相对于支撑部构件152的路径位于相对于轴28形成非垂直角度的平面内。 In the illustrated example, the radiation source 18 with respect to the path of the supporting member 152 is located in the plane with respect to the shaft 28 are formed non-perpendicular angle.

[0065] 另外,在另一示例中,从图3E所示的位置,支撑部构件160以及第一部分50和第二部分52可以一起围绕轴28旋转180°以实现图3F所示的配置。 [0065] Further, in another example, from the position shown 3E, the support member 160 and a portion of the first portion 50 and second portion 28 rotates the shaft 52 may be arranged as shown in FIG. 3F 180 ° around together to implement.

[0066] 应指出,在任何由部件50、52、160形成的给定配置,第二部分52可以相对于两个毗邻部件50、160围绕轴54旋转以围绕患者转动放射源18,使得能量可以从各种角位置朝着患者递送。 [0066] Note that in any given configuration by a member 50, 52 is formed, the second portion 52 with respect to two adjacent parts 50, 160 about the rotational shaft 54 ​​is rotated around the patient to the radiation source 18, so that energy can be delivered from a variety of angular positions towards the patient. 例如,从图3D所示的配置,第二部分52可以相对于部件50、160围绕轴54旋转,以围绕患者转动放射源18。 For example, the configuration shown in FIG. 3D, the second portion 52 relative to member 50, 160 about the rotational shaft 54, to rotate the radiation source 18 about the patient. 这种情况下,放射源18的旋转路径位于相对于轴28形成非垂直角度的平面内。 In this case, the rotational path of the radiation source 18 located in the plane with respect to the shaft 28 are formed non-perpendicular angle. 图3G示出当图3D的部件52围绕轴54旋转90°时系统10的配置。 3G shows when the member 52 of FIG. 3D shaft 54 ​​is rotated about 90 ° to 10 the system configuration.

[0067] 另外,在任何由部件50、52、160形成的给定配置,所有三个部件50、52、160可以相对于支撑部150、152围绕轴28旋转以围绕患者转动放射源18,使得能量可以从各种角位置朝着患者递送。 [0067] Further, in any given configuration formed by the components 50, 52, all three components 50, 52 relative to the support portions 150, 152 to rotate about the shaft 28 rotates the radiation source 18 around the patient, so that energy may be delivered from a variety of angular positions towards the patient. 例如,从图3D所示的配置,部件50、52、160可以一起围绕轴28旋转,以围绕患者转动放射源18。 For example, the configuration shown in FIG. 3D, members 50, 52 together around the shaft 28 can be rotated to rotate the radiation source 18 about the patient. 这种情况下,放射源18的旋转路径位于垂直于轴28的平面内。 In this case, the rotational path of the radiation source 18 lies in a plane perpendicular to the axis 28. 图3C示出当图3D的部件50、52、160围绕轴28旋转90°时系统10的配置。 FIG. 3C shows that when 3D of FIG. 50, 52 about the shaft member 28 is rotated 90 ° to 10 the system configuration.

[0068] 应指出,系统10可以实现的可能配置不限于所描述的示例,并且系统10在其它实施例中可以实现其它配置。 [0068] It should be noted, the system 10 may be configured to achieve the described examples are not limited to, the system 10 and other configurations may be implemented in other embodiments. 例如,图3H示出通过转动支撑部构件160和/或部分52可以实现的另一配置。 For example, FIG 3H shows another configuration by rotating the support member 160 and / or the portion 52 may be implemented.

[0069] 在一个或多个实施例中,部件50、52、160围绕轴28的旋转可以通过启动电机170(图3B)来实现。 [0069] In one or more embodiments, the rotation shaft member 28 may be achieved by a starter motor 170 (FIG. 3B) 50,52,160 around. 在部件50、52、160围绕轴28旋转时,第二部分52可以相对于两个毗邻部件50、160保持位置固定。 50, 52 in the shaft member 28 rotates relative to the second portion 52 adjacent to the two members 50, 160 maintain a fixed position around. 这可以使用锁定机构来实现,该锁定机构相对于第一部分50和支撑部构件160将第二部分52锁定就位。 This may be achieved using a locking mechanism, the locking mechanism 50 with respect to the first portion and the support member portion 160 locked in place the second portion 52. 可替换地,在部件50、52、160围绕轴28旋转时,第二电机172也可以启动以相对于两个毗邻部件50、160转动第二部分52。 Alternatively, the members 50, 52 about the shaft 28 rotates, the second motor 172 may be activated to two adjacent members 50, 160 relative to the second portion 52 is rotated. 同时启动电机170、172是有利的,因为它允许系统10在更短时间量内(与当电机170、172顺序启动时相比)形成期望配置,由此减少患者的治疗时间。 While the starter motor 170, 172 is advantageous because it allows the system 10 is formed in a shorter time the desired amount of configuration (170, 172 than when the motor starting sequence), thereby reducing the treatment time of the patient.

[0070] 如所讨论的,系统10可以包括成像器178和相应的成像源179。 [0070] As discussed, the system 10 may include an imaging device 178 and the corresponding imaging source 179. 图31图示系统10,尤其与系统10的其余部件关联示出成像器178和成像源179。 FIG. 31 illustrates a system 10, in particular associated with the remaining components of the imaging system 10 is shown imaging sources 178 and 179. 尽管一组成像器178和成像源179示于此示例中,但是在其它实施例中,系统10可以具有相对于彼此以90° (或者以任何其它角度)放置的两组成像器178和成像源179。 Although the composition of a source image 178 and image 179 shown in this example, but in other embodiments, the system 10 may have relative to one another 90 ° (or at any other angle) placed two imagers 178 and the imaging source 179.

[0071] 如所讨论的,系统10可以可选地包括一个或多个屏蔽件90。 [0071] As discussed, the system 10 may optionally include one or more shields 90. 图3J图示图3B的系统10,尤其示出具有屏蔽件90的系统10。 Figure 3J illustrates the system 10 of FIG. 3B, in particular, shows a system 90 of the shield 10. 屏蔽件90具有右部分190和左部分192。 The shield member 90 has a right portion 190 and left portion 192. 在使用期间,屏蔽件90的右部分190和左部分192可以在患者支撑部22的下方和/或紧挨着定位器64而被收缩。 During use, the shield member 90 in the right portion 190 and left portion 192 can be below the patient support 22 and / or next to the retainer 64 is shrunk. 在患者已经被放置在患者支撑部22上之后,屏蔽件90的右部分190和左部分192可以被机械地向上移动到封闭位置,由此形成完全围绕患者的封闭空间。 The patient has been placed in the patient after the supporting portion 22, the shield member 90 of the right portion 190 and left portion 192 may be mechanically moved upwardly to the closed position, thereby forming a closed space completely surrounds the patient.

[0072] 图3K图示系统10的另一变型,尤其示出具有多个屏蔽件90a_90c的系统。 [0072] FIG. 3K illustrates another variant the system 10, particularly illustrating a plurality of systems having 90a_90c shields. 每个屏蔽件90a、90b具有左部分和右部分,它们可以在患者支撑部22以下和/或紧挨着定位器64而被收缩。 Each shield member 90a, 90b has a left and right portions, they may be in the patient support 22 and / or the next retainer 64 is contracted. 在患者已经被放置在患者支撑部22上之后,每个屏蔽件90a、90b的左部分和右部分可以被机械地向上移动到封闭位置。 The patient has been placed in the patient after the supporting portion 22, each shield member 90a, left and right portions 90b may be mechanically moved upwardly to the closed position. 另外,屏蔽件90c可以被放置在患者支撑部22以下的开口位置。 Further, the shield member 90c may be placed in an open position below the patient support portion 22. 在患者已经被放置在患者支撑部22上之后,屏蔽件90c可以围绕铰链旋转以将屏蔽件90c摆动到封闭位置。 The patient has been placed in the patient after the supporting portion 22, the shield member 90c can be about the hinge 90c rotates to swing the shield member to the closed position. 屏蔽件90a-90c共同地起到阻挡(衰减)由放射源18的操作导致的、从囊舱16发射出来的放射的作用,同时允许患者的各部分从系统10外部是可见的。 The shield member 90a-90c collectively act as a barrier (attenuated) by the operation of the radiation source 18, the role of emitted radiation from the capsule 16 while allowing portions of the patient 10 is visible from outside the system. 在一些实施例中,屏蔽壁(例如铅玻璃)可以耦合在屏蔽件90a、90b之间以进一步衰减放射。 In some embodiments, the shielding wall (e.g. lead glass) may be coupled between the shielding member 90a, 90b in order to further attenuate radiation.

[0073] 图4图示依据其它实施例的另一放射系统10。 [0073] Figure 4 illustrates another radiation system according to other embodiment 10. 图4的放射系统10类似于图1的系统10,除了囊舱16具有不同配置。 FIG 4 the radiation system 10 system 10 is similar to Figure 1, except that the capsule 16 has a different configuration. 如图所示,囊舱16具有围绕患者42的尺寸。 As shown, the capsule 16 has a size of 42 around the patient. 囊舱16具有第一部分50以及相对于第一部分50围绕轴54旋转的第二部分52。 The capsule having a first portion 50 and 16 with respect to the first portion 50 rotates about the axis 54 of the second portion 52. 囊舱16的第二部分52承载放射源18,放射源18被配置成递送治疗放射和/或诊断放射。 The second portion 16 of the capsule 52 carrying the radiation source 18, the radiation source 18 is configured to deliver radiation therapy and / or diagnostic radiology. 在使用期间,囊舱16的第二部分52围绕轴54旋转,以由此相对于期望被治疗和/或成像的患者42的部分40将放射源18放置在不同的龙门位置。 During use, the second portion 52 of the capsule 54 is rotated about the axis 16, with respect to the desired thereby the patient being treated and / or the imaging portion 4042 of the radiation source 18 at different gantry positions. 放射源18可以是与参考图1所讨论的放射源相同的放射源18。 The radiation source 18 may be the same radiation source and the radiation source discussed with reference to FIG 18. 在图示的实施例中,SID/SAD小于800mm,并且更优选地小于600mm,并且甚至更优选地约为415mm(415mm±40mm)。 In the embodiment illustrated, SID / SAD is less than 800mm, and more preferably less than 600mm, and even more preferably about 415mm (415mm ± 40mm). 另外,在一些实施例中,放射系统10的SID/SAD值小于现有放射机器中的SID/SAD值。 Further, in some embodiments, SID / SAD value is smaller than the radiation system 10 in conventional radiotherapy machine SID / SAD value. 在其它实施例中,SID/SAD可以具有其它值(例如大于6OOmm的值)。 In other embodiments, SID / SAD may have other values ​​(e.g. the value greater than 6OOmm).

[0074] 在一些实施例中,囊舱16可以可选地被配置成也围绕垂直于轴54的轴旋转。 [0074] In some embodiments, the capsule 16 may alternatively be configured to also rotate the shaft 54 ​​about a vertical axis. 例如,在一些实施例中,囊舱16也可以被配置成围绕与系统10的等中心点200吻合并且垂直于轴54从图的纸面向外延伸的轴旋转。 For example, in some embodiments, the capsule 16 may be configured to rotate about the shaft 200 and the center point of anastomosis system 10 is perpendicular to the axis 54 and extending outwardly from the plane of the drawing. 支撑部22可以被配置成平移患者42 (例如,在箭头202代表的方向上),以由此将患者42的不同部分放置在等中心点200。 The supporting portion 22 may be configured to translate the patient 42 (e.g., in the direction represented by arrow 202), thereby to different portions of the patient 42 is placed in the isocenter 200.

[0075] 应指出,任何参考图1的实施例讨论的与屏蔽有关的特征可以被包括在图4的实施例中。 [0075] It should be noted, with the shielding features related to any of the embodiments discussed with reference to Figure 1 may be included in the embodiment of FIG. 4. 例如,在一些实施例中,囊舱16包括屏蔽材料,屏蔽材料被配置成阻挡由放射源18的操作导致的至少一些放射。 For example, in some embodiments, the capsule 16 comprises a shielding material, shielding material configured to block at least some of the radiation from the radiation source 18 is operating. 在一些实施例中,屏蔽材料可以用于制作囊舱16的壁。 In some embodiments, the shielding material may be used to create a wall 16 of the capsule. 在其它实施例中,屏蔽材料可以耦合到囊舱16的壁。 In other embodiments, the shielding material may be coupled to a wall of the capsule 16. 例如,屏蔽材料可以耦合到囊舱16的壁的外表面,囊舱16的壁的内表面,或者可以是嵌在囊舱16的壁内的层。 For example, shielding material may be coupled to an outer surface of the wall of the capsule 16, the inner surface of the wall of the bladder chamber 16, or may be embedded in the wall of the capsule 16 of the layer. 此外,在其它实施例中,屏蔽材料可以是耦合到囊舱16的多层的形式,其具有耦合到囊舱16的壁的外表面的一个或多个层,嵌在囊舱16的壁内的一个或多个层,耦合到囊舱16的壁的内表面的一个或多个层,或者其组合。 Further, in other embodiments, the shielding material may be coupled to form a multilayer capsule 16, an outer wall having a surface which is coupled to the capsule 16 or a plurality of layers, embedded in the wall of the capsule 16 one or more layers, is coupled to an inner surface of the wall of the capsule 16 or more layers, or combinations thereof. 另外,在一些实施例中,屏蔽材料可以被配置(例如具有某一材料密度、某一几何形状和/或某一厚度)以阻挡放射,使得它减少从其行进经过的由放射源18的操作导致的放射(例如,光子/荷电粒子,诸如电子、中子等)的至少98%,以及更优选地至少99.9%,以及甚至更优选地至少99.999%。 Further, in some embodiments, shielding material may be configured (e.g., a material having a density, a geometry and / or a thickness) to block the radiation so that it travels through the reduced therefrom by the operation of the radiation source 18 Radiation resulting (e.g., photons / charged particles, such as electrons, neutrons, etc.) of at least 98%, and more preferably at least 99.9%, and even more preferably at least 99.999%. 在另外的实施例中,屏蔽材料可以被配置成阻挡由放射源18的操作导致的足够数量的放射,使得它消除对在设施建筑物(诸如在医院)提供屏蔽的需求。 In a further embodiment, the shielding material may be configured to block sufficient amount of radiation by the operation of the radiation source 18, such that it eliminates the need for installation in a building (such as in a hospital) shielding provided. 这种特征是有利的,因为它允许放射系统10可用在建筑物内的任何位置,或者可用在任何设施,而不要求对建筑物进行昂贵改造以提供放射屏蔽。 This feature is advantageous because it allows the radiation system 10 may be used in any location within the building, or at any facility, without requiring expensive buildings engineered to provide a radiation shield. 在其它实施例中,不是完全消除建筑物处的屏蔽,屏蔽材料可以被配置成阻挡由放射源18的操作导致的足够数量的放射,使得它减少在建筑物处的屏蔽要求的显著数量(例如至少50%,以及更优选地至少90% )。 In other embodiments, the shield building is not completely eliminated at the shielding material may be configured to block sufficient amount of radiation by the operation of the radiation source 18, such that it significantly reduces the number of shielding requirements at a building (e.g. at least 50%, and more preferably at least 90%). 这种特征是有利的,因为它允许放射系统10可用在建筑物内的任何位置,或者可用在任何设施,而对建筑物进行最小改造以提供放射屏蔽。 This feature is advantageous because it allows the radiation system 10 may be used in any location within the building, or at any facility, and the building engineered to provide minimal radiation shield.

[0076] 另外,在另外的实施例中,图4的系统10可以可选地包括一个或多个屏蔽件90,如类似地讨论的那样。 [0076] Further, in another embodiment, the system 10 of FIG. 4 may optionally include one or more shields 90, as similarly discussed.

[0079] 在一些实施例中,囊舱16可以可选地被配置成也围绕垂直于轴54的轴旋转。 [0079] In some embodiments, the capsule 16 may alternatively be configured to also rotate the shaft 54 ​​about a vertical axis. 例如,在一些实施例中,囊舱16也可以被配置成围绕与系统10的等中心点200吻合并且垂直于轴54从图的纸面向外延伸的轴旋转。 For example, in some embodiments, the capsule 16 may be configured to rotate about the shaft 200 and the center point of anastomosis system 10 is perpendicular to the axis 54 and extending outwardly from the plane of the drawing. 在另一示例中,囊舱16可以被配置成围绕轴300旋转,轴300从等中心点200偏离并且从图的纸面向外在垂直于轴54的方向上延伸。 In another example, the capsule 16 may be configured to rotate about the shaft 300, shaft 300 deviates from the isocentre 200 and extends outwardly from the plane of the drawing in a direction perpendicular to the shaft 54. 在一些实施例中,囊舱16内部的患者支撑部22可以通过轴杆/铰链耦合到囊舱16外部的结构支撑部12,该轴杆/铰链延伸穿过与支撑部12连接的囊舱16的壁。 Support portion in some embodiments, the support portion patient inside the capsule 1622 through the shaft / hinge coupled to the capsule 16 outside 12, the shaft / hinge extension capsule through the support portion 12 is connected to 16 wall. 这种配置允许当囊舱16围绕穿过等中心点200的轴或轴300旋转时,患者支撑部22相对于支撑部12保持旋转固定。 This configuration allows 16 when the capsule 300 rotates about a shaft or the like passing through the center point 200, the patient support 22 relative to the support portion 12 remains rotationally fixed. 这种配置还允许囊舱16相对于患者支撑部22旋转,而不在其旋转时随其承载患者支撑部22。 This configuration also allows the capsule 16 relative to the patient support rotating portion 22 without carrying along with patient support 22 as it rotates. 支撑部22可以被配置成平移患者42 (例如在箭头202代表的方向上),以由此将患者42的不同部分放置在等中心点200。 The supporting portion 22 may be configured to translate the patient 42 (e.g., in the direction represented by arrow 202), thereby to different portions of the patient 42 is placed in the isocenter 200. 支撑部22也可以被配置成以不同的自由度移动,诸如参考图1的实施例所描述的那些自由度。 The supporting portion 22 may be configured to move in different degrees of freedom, the degree of freedom of those embodiments such as the embodiment described with reference to FIG.

[0080] 应指出,任何与参考图1的实施例讨论的屏蔽有关的特征可以被包括在图5的实施例中。 [0080] It should be noted that any features related to shielding discussed with reference to the embodiment of FIG. 1 may be included in the embodiment of FIG. 5. 例如,在一些实施例中,囊舱16包括屏蔽材料,屏蔽材料被配置成阻挡由放射源18的操作导致的至少一些放射。 For example, in some embodiments, the capsule 16 comprises a shielding material, shielding material configured to block at least some of the radiation from the radiation source 18 is operating. 在一些实施例中,屏蔽材料可以用于制作囊舱16的壁。 In some embodiments, the shielding material may be used to create a wall 16 of the capsule. 在其它实施例中,屏蔽材料可以耦合到囊舱16的壁。 In other embodiments, the shielding material may be coupled to a wall of the capsule 16. 例如,屏蔽材料可以耦合到囊舱16的壁的外表面,囊舱16的壁的内表面,或者可以是嵌在囊舱16的壁内的层。 For example, shielding material may be coupled to an outer surface of the wall of the capsule 16, the inner surface of the wall of the bladder chamber 16, or may be embedded in the wall of the capsule 16 of the layer. 此外,在其它实施例中,屏蔽材料可以是耦合到囊舱16的多层的形式,其具有耦合到囊舱16的壁的外表面的一个或多个层,嵌在囊舱16的壁内的一个或多个层,耦合到囊舱16的壁的内表面的一个或多个层,或者其组合。 Further, in other embodiments, the shielding material may be coupled to form a multilayer capsule 16, an outer wall having a surface which is coupled to the capsule 16 or a plurality of layers, embedded in the wall of the capsule 16 one or more layers, is coupled to an inner surface of the wall of the capsule 16 or more layers, or combinations thereof. 另外,在一些实施例中,屏蔽材料可以被配置(例如具有某一材料密度、某一几何形状和/或某一厚度)以阻挡放射,使得它减少从其行进经过的由放射源18的操作导致的放射(例如,光子/荷电粒子,诸如电子、中子等)的至少98%,以及更优选地至少99.9%,以及甚至更优选地至少99.999%。 Further, in some embodiments, shielding material may be configured (e.g., a material having a density, a geometry and / or a thickness) to block the radiation so that it travels through the reduced therefrom by the operation of the radiation source 18 Radiation resulting (e.g., photons / charged particles, such as electrons, neutrons, etc.) of at least 98%, and more preferably at least 99.9%, and even more preferably at least 99.999%. 在另外的实施例中,屏蔽材料可以被配置成阻挡由放射源18的操作导致的足够数量的放射,使得它消除对在设施建筑物(诸如在医院)提供屏蔽的需求。 In a further embodiment, the shielding material may be configured to block sufficient amount of radiation by the operation of the radiation source 18, such that it eliminates the need for installation in a building (such as in a hospital) shielding provided. 这种特征是有利的,因为它允许放射系统10可用在建筑物内的任何位置,或者可用在任何设施,而不要求对建筑物进行昂贵改造以提供放射屏蔽。 This feature is advantageous because it allows the radiation system 10 may be used in any location within the building, or at any facility, without requiring expensive buildings engineered to provide a radiation shield. 在其它实施例中,不是完全消除建筑物处的屏蔽,屏蔽材料可以被配置成阻挡由放射源18的操作导致的足够数量的放射,使得它减少在建筑物处的屏蔽要求的显著数量(例如至少50%,以及更优选地至少90% )。 In other embodiments, the shield building is not completely eliminated at the shielding material may be configured to block sufficient amount of radiation by the operation of the radiation source 18, such that it significantly reduces the number of shielding requirements at a building (e.g. at least 50%, and more preferably at least 90%). 这种特征是有利的,因为它允许放射系统10可用在建筑物内的任何位置,或者可用在任何设施,而对建筑物进行最小改造以提供放射屏蔽。 This feature is advantageous because it allows the radiation system 10 may be used in any location within the building, or at any facility, and the building engineered to provide minimal radiation shield.

[0081] 另外,在另外的实施例中,图5的系统10可以可选地包括一个或多个屏蔽件90,如类似地讨论的那样。 [0081] Further, in another embodiment, the system 10 of FIG 5 may optionally include one or more shields 90, as similarly discussed. (多个)屏蔽件90和囊舱16可以协同阻断由放射源18的操作导致的放射的至少98%,以及优选地至少99.9%,以及甚至更优选地至少99.999%。 (S) the shield 90 and the capsule 16 may cooperate to block radiation by the operation of the radiation source 18 is at least 98%, and preferably at least 99.9%, and even more preferably at least 99.999%. 在一些实施例中。 In some embodiments. 在其它实施例中,(多个)屏蔽件90本身可以阻挡由放射源18的操作导致的大多数放射。 In other embodiments, (s) itself may block the shield 90 by the operation of most of the radiation of the radiation source 18.

[0082] 在一些实施例中,图5的系统10的部件(例如囊舱16、部分52等)的移动可以基于治疗计划来执行。 [0082] In some embodiments, the moving member 10 of the system of Figure 5 (e.g., capsule 16, section 52, etc.) may be performed based on a treatment plan. 另外,在一些实施例中,当确定将使用系统10实施的治疗计划时,与系统10的移动部分的自由度关联的移动约束可以被结合到治疗计划中。 Further, in some embodiments, when determining a treatment plan using the system 10 embodiment, the degree of freedom of movement constraints associated with the moving part of the system 10 may be incorporated into the treatment plan.

[0083] 图6图示依据其它实施例的另一放射系统10。 [0083] FIG. 6 illustrates another radiation system according to other embodiment 10. 系统10包括患者支撑部22、龙门500、耦合到龙门500的放射源18以及用于配置由放射源18提供的放射(例如改变放射束的形状)的准直器19。 The system 10 includes a patient supporting portion 22, the gantry 500, the radiation source 500 is coupled to the gantry 18, and is configured by a collimator for the radiation source 18 provides radiation (e.g., changing the shape of the radiation beam) 19. 在图示的实施例中,患者支撑部22被配置成以直立姿势支撑患者42。 In the illustrated embodiment, the patient support 22 is configured to support a patient 42 in an upright posture. 在一个实施方式中,患者支撑部22可以被实施为医用椅。 In one embodiment, the patient support 22 may be embodied as a medical chairs. 患者支撑部22还被配置成在使用期间通过定位器64围绕轴510旋转,使得患者42可以相对于放射源18旋转。 The patient support portion 22 is further arranged, during use about a shaft 510 rotated by actuator 64, so that the patient 42 with respect to the radiation source 18 rotates. 因为患者42通过患者支撑部22旋转,所以承载放射源18的龙门500不需要旋转。 Because the patient support portion 42 is rotated by 22 patients, the carrier 500 need to rotate the gantry 18 of the radiation source. 相反,龙门500被配置成以向上或向下的姿势竖直地移动,使得放射源18可以递送放射到患者42的(多个)不同部分。 In contrast, the gantry 500 is configured to move upward or vertically downward gestures, so that the radiation can be delivered to a radiation source 18 (s) of different portions of the patient 42. 这种情况下,龙门500可以例如滑动耦合到竖直轨。 In this case, the gantry 500 may be coupled to the vertical such as a sliding rail.

[0084] 在其它实施例中,定位器64也可以被配置成竖直地向上或向下移动患者支撑部 [0084] In other embodiments, the locator 64 may also be configured to the patient support portion vertically upward or downward

22。 twenty two. 这种情况下,龙门500不需要竖直地移动(例如,龙门500可以被固定地安装到一种结构,诸如系统10的部件、房间的一部分等)。 In this case, the gantry 500 does not need to be moved vertically (e.g., gantry 500 may be fixedly mounted to a structure member, such as a part of the room, etc. The system 10). 然而,在一些实施例中,龙门500可以可选地被配置成以任何方式竖直地移动。 However, in some embodiments, the gantry 500 may optionally be configured to be moved vertically in any way. 在另外的实施例中,龙门500可以可选地被配置成相对于患者42倾斜。 In a further embodiment, the gantry 500 may optionally be configured to be inclined relative to the patient 42. 例如,在一些实施例中,龙门500可以被配置成围绕轴514旋转,使得放射源18可以在不同角位置朝着患者42递送放射。 For example, in some embodiments, the gantry 500 may be configured to rotate about the shaft 514, so that the radiation source 18 may deliver radiation towards the patient 42 at different angular positions.

[0085] 如图所示,龙门500包括门512,用于允许患者42进入由龙门500围绕的空间502内。 [0085] As shown, the gantry 500 includes a door 512 for allowing the patient 42 into the space surrounded by the gantry 500,502. 门512可以可选地包括成像器100,使得当门512封闭时,成像器100相对于放射源18处于操作位置。 Gate 512 may optionally include an imaging device 100, such that when the door 512 is closed, the imager 100 with respect to the radiation source 18 is in the operating position. 在使用期间,来自放射源18的放射进入患者42并且离开患者42以到达成像器100。 During use, radiation from the radiation source 18 into the patient 42 and away from the patient 42 to reach the imager 100. 成像器100响应于在其上接收的放射而生成图像数据。 The imager 100 in response to radiation received thereon and generates image data. 放射在一些实施例中可以是治疗放射,或者在其它实施例中可以是诊断放射。 In some embodiments, the radiation may be radiation therapy, or in other embodiments may be diagnostic radiology. 在一些实施例中,图像数据可以在使用诊断放射的治疗过程之前(例如在治疗放射被递送到患者42之前)生成以设定患者42。 In some embodiments before, the image data may be used in the diagnosis of radiation therapy (e.g., radiation treatment is delivered to the patient prior to 42) to set the patient 42 generated. 在其它实施例中,图像数据可以在治疗过程期间生成以强化治疗放射递送的准确性。 In other embodiments, the image data may be generated to enhance the accuracy of the delivery of radiation therapy during the course of treatment. 在另外的实施例中,图像数据可以由处理器80处理,处理器80基于经处理的图像数据调整治疗计划。 In a further embodiment, the image data may be processed by processor 80, processor 80 to adjust the treatment plan based on the processed image data. 例如,如果处理器80根据图像数据确定一部分目标区域未在接收足够的放射,和/或如果关键(例如健康的)组织正在接收太多的放射,那么处理器80可以随后调整治疗计划,使得将来的治疗放射递送将导致更多放射被递送到目标区域和/或更少放射被递送到关键组织。 For example, if the processor 80 determines a portion of the target area is not receiving enough radiation, and / or if the key (eg healthy) tissue is receiving too much radiation, the processor 80 can then adjust the treatment plan, so that in the future based on image data the delivery of radiation therapy will result in more radiation being delivered to key organizational goal area and / or less radiation being delivered to.

[0086] 放射源18 可以是与参考图1所讨论的放射源相同的放射源18。 Same radiation source the radiation source [0086] The radiation source 18 may be discussed with reference to FIG. 1 as 18. 在图示的实施例中,SID/SAD小于800mm,以及更优选地小于600mm,以及甚至更优选地约为415mm(415mm±40mm)。 In the embodiment illustrated, SID / SAD is less than 800mm, and more preferably less than 600mm, and even more preferably about (415mm ± 40mm) 415mm. 另外,在一些实施例中,放射系统10的SID/SAD值小于现有放射机器中的SID/SAD值。 Further, in some embodiments, SID / SAD value is smaller than the radiation system 10 in conventional radiotherapy machine SID / SAD value. 这种配置允许放射源18提供与现有治疗放射源相比更少的放射能量,并且仍然足够治疗目标(例如肿瘤)。 This configuration allows the radiation source 18 provides less as compared with the conventional radiant energy treatment radiation source, and still sufficient to treat the target (e.g. a tumor). 另外,由于能量要求的减少,设施建筑物所需要的屏蔽的量显著减少,或者可以被消除。 Further, due to the reduced energy requirements, the amount of shielding required for building facilities significantly reduced or may be eliminated. 在其它实施例中,SID/SAD可以具有其它值(例如大于600mm 的值)。 In other embodiments, SID / SAD may have other values ​​(e.g. the value greater than 600mm).

[0087] 在图示的实施例中,放射系统10还包括围绕龙门500的屏蔽件90。 [0087] In the illustrated embodiment, the radiation system 10 further includes a shield member 90 around the gantry 500. 屏蔽件90被配置成阻挡由放射源18的操作导致的至少一些放射。 The shield 90 is configured to block at least some of the radiation from the radiation source 18 is operating. 在一些实施例中,屏蔽件90可以被配置(例如具有某一材料密度、某一几何形状和/或某一厚度)以阻挡放射,使得它减少从其行进经过的由放射源18的操作导致的放射(例如,光子/荷电粒子,诸如电子、中子等)的至少98%,以及更优选地至少99.9%,以及甚至更优选地至少99.999%。 In some embodiments, the shield 90 may be configured (e.g., a material having a density, a geometry and / or a thickness) to block the radiation so that it travels through its reduction is caused by the operation of the radiation source 18 radiation (e.g., photons / charged particles, such as electrons, neutrons, etc.) at least 98%, and more preferably at least 99.9%, and even more preferably at least 99.999%. 在另外的实施例中,屏蔽件90可以被配置成阻挡由放射源18的操作导致的足够数量的放射,使得它消除对在设施建筑物(诸如在医院)提供屏蔽的需求。 In a further embodiment, the shield 90 may be configured to block sufficient amount of radiation by the operation of the radiation source 18, such that it eliminates the need for installation in a building (such as in a hospital) shielding provided. 这种特征是有利的,因为它允许放射系统10可用在建筑物内的任何位置,或者可用在任何设施,而不要求对建筑物进行昂贵改造以提供放射屏蔽。 This feature is advantageous because it allows the radiation system 10 may be used in any location within the building, or at any facility, without requiring expensive buildings engineered to provide a radiation shield. 在其它实施例中,不是完全消除建筑物处的屏蔽,屏蔽件90可以被配置成阻挡由放射源18的操作导致的足够数量的放射,使得它减少在建筑物处的屏蔽要求的显著数量(例如至少50%,以及更优选地至少90%)。 In other embodiments, the shield building is not at completely eliminating, the shield 90 may be configured to block sufficient amount of radiation by the operation of the radiation source 18, such that it significantly reduces the number of shielding requirements at a building ( such as at least 50%, and more preferably at least 90%). 这种特征是有利的,因为它允许放射系统10可用在建筑物内的任何位置,或者可用在任何设施,而对建筑物进行最小改造以提供放射屏蔽。 This feature is advantageous because it allows the radiation system 10 may be used in any location within the building, or at any facility, and the building engineered to provide minimal radiation shield.
